Dario Amodei
CEO & Co-founder, Anthropic
About
Dario Amodei is the CEO and co-founder of Anthropic, an AI safety company. Before founding Anthropic in 2021, he served as VP of Research at OpenAI, where he led the development of GPT-2 and GPT-3. His work focuses on developing AI systems that are safe, beneficial, and understandable, with particular emphasis on Constitutional AI and interpretability research.
Key Contributions
- Co-founded Anthropic after leaving OpenAI, making AI safety and interpretability central to a frontier-model company
- Led Anthropic's Claude product line and popularized Constitutional AI as an alternative to pure human-feedback training
- Co-authored 'Concrete Problems in AI Safety' (2016), which helped define practical failure modes for learning systems
- Contributed to OpenAI's GPT-2 and GPT-3 work, including the GPT-3 paper 'Language Models are Few-Shot Learners'
- Helped move AI safety from a research subculture into the executive strategy and governance of frontier labs
- Advanced Anthropic's responsible-scaling and AI Safety Level framing, while drawing scrutiny for competing in the same high-speed frontier race it warns about

Anthropic Designated a Supply Chain Risk
The Trump administration designates Anthropic a 'supply chain risk to national security' — a label previously reserved for foreign adversaries like Huawei — after the company refuses to remove two guardrails from its $200M Pentagon contract: no mass surveillance of Americans, and no fully autonomous weapons. Defense Secretary Hegseth issues the designation hours after a Friday 5:01 PM deadline passes without agreement. Trump orders all federal agencies to cease using Anthropic technology. In an exclusive CBS interview that evening, CEO Dario Amodei calls the action 'retaliatory and punitive,' vows to challenge it in court, and declares: 'We're gonna be fine.' Sam Altman and workers across OpenAI and Google voice support for Anthropic's position. The crisis marks the most consequential clash between an AI company and the U.S. government over the boundaries of military AI use.
"We have these two red lines. We've had them from day one. We are still advocating for those red lines. We're not going to move on those red lines."
The Adolescence of Technology
Anthropic CEO warns humanity is entering the most dangerous window in AI history. The 20,000-word essay argues AI as capable as all humans will arrive within two years, predicts 50% of entry-level white collar jobs eliminated in 1-5 years, and reveals concerning 'alignment faking' behaviors in Claude 4 Opus testing.
Machines of Loving Grace
Anthropic CEO outlines an optimistic vision where AI could compress 50-100 years of progress into 5-10 years across biology, health, economic development, and governance—if developed responsibly.

Chris Olah
CollaboratedCo-founder & Interpretability Lead, Anthropic
Their partnership predates both Anthropic and the LLM era: in 2016 they co-wrote 'Concrete Problems in AI Safety,' which turned vague fear of superintelligence into five researchable engineering failures. Five years later they left OpenAI together among Anthropic's seven founders, where Amodei runs the company that ships the models and Olah runs the team trying to read what is inside them. The bet that safety is an empirical science rather than a philosophical position runs from that paper straight through the lab.

Sam Altman
CollaboratedCEO, OpenAI
Amodei was OpenAI's VP of Research under Altman from 2016 and the last author on the GPT-3 paper, before leaving in 2021 over differences of direction to found the competitor built around the safety case. The relationship has an unresolved coda: in November 2023 OpenAI's board approached Amodei about replacing Altman and merging the two labs, and he declined both. Two men who built the same technology and have never agreed on who should be trusted to steward it.

Benjamin Mann
CollaboratedCo-founder, Anthropic
Mann is the second author of 'Language Models are Few-Shot Learners' and Amodei signs it last — the two of them bracketing the author list of the paper that made scaling impossible to dismiss. Both then left OpenAI in the same 2021 exodus to found Anthropic. The pair marks the seam this site keeps returning to: the people who proved scaling works are the same people who concluded it needed a different institutional home.

Jack Clark
CollaboratedCo-founder & Head of Policy, Anthropic
Clark ran policy at OpenAI while Amodei ran research; both appear on the GPT-3 author list, and both left in 2021 among Anthropic's seven founders. What makes the pairing worth reading is the division of labor it created — Amodei arguing the exponential in essays and testimony, Clark translating it weekly in Import AI for the people who write the rules. Governance here is not an external check on the lab; it is staffed from inside it.
